Science institutions measure local temperature in many ways. On land, thermometers affixed to tens of thousands of weather stations give us precise air temperature readings. Ships and buoys floating in the ocean capture temperatures at the sea surface. These individual measurements tell us the temperature at any one place for that day and time.

Just below that about 12-14 inches is the top of the A coil. I'll just drill a hole about 2 inches from the top and measure the temp and compare with the tech's other data. I think the temp rise the first time around was about 65 degrees and the second tech's was 70 degrees. The furnace calls for 55-85 degree temp rise.

Temperature Rise Testing. Gauging the temperature performance of a cable assembly is done using a temperature rise test. This test is governed by UL 310, which states that the maximum current carrying capacity of a connector (aka, ampacity) is based on the current that causes the connector body temperature to rise by 30 degrees from its natural ...

Temperature measures the degree of hotness or coldness of a body. It is measured using a device called a thermometer. There are several types of thermometers, each of which works differently, but they all measure temperature by looking at how certain materials change under different conditions. The most common type of thermometer is the mercury thermometer.

The temperature of the thermometer is then compared with the temperature of the surface. At the National Laboratory for Temperature at RISE, there is a surface temperature calibrator that is widely used for calibrations from room temperature up to 600 degrees. "But we get requests for calibration at higher temperatures than that.

The plastic softens in temperatures of approximately 75 °C and spontaneous combustion occurs at approximately 140 °C. The CRUSHER offers the solution for this. When exposed to fire the CRUSHER forms a self-adhering mass that fully seals the transit opening and does not offer fire the chance to spread further. ... RISE/ULTRA C-fit crushers ...

For FR-2 it might be 105°C, so the limit might be 35°C rise. More normal practice is to allow for 20-30°C to keep the PCB from getting all discolored and weak over time and there might be issues with component life if you add too much heat. It's conceivable UL approvals might be complicated with internal temperatures exceeding 105°C.

$begingroup$ As @ox6d64 said, you can't know temperature without thermal resistance. But you can start with power dissipation per length to get a feel for whether it is a issue or not. Look up the resistivity of copper and determine what the resistance of 2.5 mm^2 for one foot is.
